LINOTYPE- SPECIFICATION forming part of Letters Patent No. 524,285,dated August '7, 1894.

Application filed July 8,1893. Serial No. 479,898. on model.)

Improvement in Linotype-Machines, of which the following is aspecification.

My invention relates to linotype machines in which a series of typematrices, containing individual characters, areiselected and assembledin'line, so that a linotype or slug cast or molded against the line willbear in relief the characters to print an entire line. Heretofore it hasbeen customary to cast the slug or linotype in a mold, against which thematrices were temporarily assembled so as to close the same and presenttheir characters My invention is intended to overcome the necessity forthis mold, and consists in forming the matrices with deep slots'havingthe matrices proper at the bottom, so that when a series of matrices areassembled side by side, their slots standing in line, will form a alinotype. Matrices thus constructed will serve both as molds and asmatrices. In other words, they will give form to the bar or linotype andalso produce the characters on its edge. The matrices may be made of anysuitable material, and of any size and external form required in orderto adapt them for use in different classes of machines, and withdifierent composing and assembling mechanisms of said machines. I,

Figure 1, is a perspective view of amatrix on my plan, adapted for usein a machine having composing and distributing devices, like those ofthe ordinary Mergenthaler linotype; and Fig. 2, is a cross-section,showing the manner in which a line of matrices will be used inconnection with produce a slug-or linotype.

A represents the body of the matrix; a a

the melting pot to slot or groove therein, and a the matrix proper. i

B represents the mouth of the melting pot arranged to close tightlyagainst the rear faces of a composed line of matrices, so as to closethe slots therein. The pot may be provided like the linotype machineswith the pump plunger 0 to deliver the molten metal into the slots ofthe matrices. The pot will be heated by a burner thereunder as usual.

The matrices herein shown may be used in combination with solid spacesof corresponding form and of suitable thicknesses, or with adjustablespaces of any suitable character adapted for use with them. In anorganized machine, suitable appliances will of course be provided forejecting t'he linotype or cast from the matrices. Thesefeatures,however, form no part of the present invention. The matrices atthe ends of the line will have their slots covered or closed by theusual clamping jaws, or other covering devices, to prevent leakage ofmetal.

What I claim as my invention is- 1 1. A linotype matrix having therein adeep slot to give form to the two opposite sides of a linotype or slug,and a matrix proper at the bottom of the said slot.

2. A combination of a series of matrices slotted as described to giveform to the opposite sides of the cast, and means for delivering moltenmetal or therein.

3. The combination of a series of matrices having slots correspondingwith the sectional form of the required linotype, and a melting potadapted to fit against and close the rear side of the matrices and todeliver molten metal into the slot thereof, substantially as described.

In testimony whereof I hereunto set my hand, this 6th day of July, 1893,in the presence of two attesting witnesses.
